Abstract: ABSTRACT                   Prepasted Wallcoverings A  wallcovering  comprises  a  substrate  carrying  a water-moistenable coating formed of at least two layers. The layer adjacent to the substrate generally comprises unswollen  particles  of  an  anionic  polymer  that  is substantially  non-swellable  in  water  and  that  is swellable in aqueous alkali and the upper layer contains an alkali which on contact with water forms an alkaline solution which swells the anionic polymer and a water soluble cationic polymer.   The anionic polymer generally comprises beads of cross-linked copolymers of lower alkyl acrylates and methacrylic acid having a molecular weight of  about  5  million.    Processes  for  producing  the wallcoverings comprise coating the substrate separately with an aqueuous dispersion of the anionic polymer and an aqueous solution containing both the cationic polymer and the  alkaline material  to  give  at  least  two  separate layers.

Abstract: ABSTRACT OF THE DISCLOSURE:            In  a  method for the production of  synthetic  gases  from carbonaceous  fuels  and oxygen-containing gases  endother-mally  reacting with the fuels,  the starting products  are reacted  in a plasma reaction zone.  In order to provide  a method by which the production of reduction gases is feasi-ble  up to the highest flow rates in an operationally  safe manner  and  by an optimum utilization of the  energy  sup-plied,  the components to be reacted are commonly conducted through  an elongate reaction chamber as a  feed  fluid.  A central  plasma  jet is formed over the total  longitudinal extension of the reaction chamber.  The arrangement,  i.e., the elongate reaction chamber,  includes a plasma electrode (cathode) on one end and a counter electrode (anode) on the other  end;  supply ducts for the feed fluid and  discharge ducts for the synthetic or reduction gases in the region of the plasma electrode end are provided.

Abstract: ABSTRACT OF THE DISCLOSURE        A method is disclosed for bonding a minute semiconductor device to the freestanding end of a flexible microcircuit.  The method generally comprises a series of steps including initially bonding the semiconductor device to a substrate for handling during the further progression of steps.  An extremely minute conductive ball is bonded to one or more conductive surfaces of the semiconductor device and an upwardly depending pigtail is formed atop each of the conductive balls.  The flexible microcircuit, having holes in predetermined locations and in numbers corresponding to the upwardly depending pigtails, is positioned atop those pigtails such that a portion of each pigtail protrudes through the flexible microcircuit.          Another minute conductive ball is thereafter applied to each of those portions of pigtails protruding through the flexible microcircuit, thus sandwiching the microcircuit between the conductive balls.  The final result is a semiconductor device attached to the distal, free end of the flexible microcircuit of sufficient minuteness such that the semiconductor and distal end of the microcircuit can be inserted into a patient's blood vessel for in vivo detection and monitoring of various parameters.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a combined servo control and jack unit which comprises a casing, an actuated piston slidably disposed in a piston chamber and having a piston rod extending outwardly of the casing.  A servo valve chamber, axially parallel to the piston chamber, has slidably mounted therein a spool and also a sleeve member which is mechanic-ally connected to the piston rod.  Shifting the spool in either axial direction directs hydraulic fluid to one or the other side of the piston, thus moving the latter until spool stopping, at which time the sleeve automatically, almost instantly, blocks off the flow in the new position.          A variable speed, gradual action of the piston is obtained without hydraulic shock or cavitation.
